This is asking which 2 paired items have the same fractional ratio I believe. So all we have to do is make ratios of price to item amount and see if they are equal.

1. 4.5/3 = 6/5

this one we divide numerator and denominator of left side by 1.5 and get:

3/2 = 6/5

this is not true so wrong

2. 5/2 = 15.25/6

2.5 = 2.5416666

sometimes easier to use calculator then reduce. But not equal so wrong.

3. 4.75/5 = 9/10

95/100 = 9/10

wrong

4. 9/4 = 13.5 / 6

4.5/2 = 4.5/2

this one is equal
